Home Equity Calculator

Home equity is the part of your home you own outright. This tool computes it as the current market value minus the single mortgage balance you enter. In real life you would also subtract any second loan or lien secured by the home.

Three figures: equity equals market value minus mortgage balance; loan to value equals balance divided by value times 100; and equity percentage equals equity divided by value times 100. All three are rounded to two decimals.

Loan to value, or LTV, is your mortgage balance divided by the home value, shown as a percent. A 250,000 balance on a 400,000 home is 62.5 percent LTV. A lower LTV usually means more equity and can mean better loan terms.

Not directly. The tool takes one balance, so it is the LTV of that single loan. For combined loan to value across a first mortgage plus a HELOC or second, add the balances together and enter the total in the mortgage balance field.

Negative equity, or being underwater, means you owe more than the home is worth. When the balance exceeds the market value the tool returns a negative equity figure, an LTV above 100 percent and a negative equity percentage, as in a 330,000 balance on a 300,000 home.

This calculator does not compute a borrowing base. Lenders typically cap the combined loan to value near 80 to 90 percent, so subtracting your current balance from that limit times the value approximates your headroom. The actual amount depends on lender, credit and income.

No. This is gross equity based on market value. If you sell, agent commissions, transfer taxes and closing fees reduce what you walk away with, so your net proceeds will be lower than the equity shown.

You supply it. The tool cannot know your home's value, so use a recent appraisal, comparable sales or a reputable online estimate. The equity and ratios are only as accurate as that value, which is an estimate until you actually sell.

Yes. Every figure is calculated in your browser and nothing is uploaded to a server. Your home value and mortgage balance never leave your device, and there is no account or login.
